Tk house is a great place to stay in Bangkok. The location is great, right next to the sky train station, and you can get from the house in no time. The house is nice, clean, good shower and a small but useful kitchen. The communication with TK and his staff is really excellent!
Our only problem was the fact that as of April 2017, in the mornings you will hear the construction work from the building next door. It starts as around 8 in the morning, even on a Sunday. It's ok, but we wish someone would have told us before we booked the apartment. We came very late at night and TK was nice enough to come so late to open the door and show us the room, but at no point did any of the people we talked to warned us about the noise in the morning. We were tired and really needed to sleep a little late.
Other than that it was a really good experience.
